CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 731,981, dated June 23, 1903.

Application filed September 26, 1902. Serial No- 124,930.. (No model) To all whmn it Wmy concern.-

Be it'knowu that I, JOHANN O. VAHJEN, a subject of the Emperor of Germany, residing in the city of New York, borough of Manhat- 5 tan, in the county and State of New York,

have invented a new and Improved Cash- Register, of which the following is a full, clear, and exact description.

My invention relates to an improvement in to cash-registers, and the purpose of the invention is to so construct the machine that it can be quickly operated and a check and duplicate check be obtained, the check proper to be automatically delivered from the machine while the duplicate check will remain locked in the machine to be examined whenever the machine is opened.

Another purpose of the invention is to so construct the machine that the amounts in- 2'0 dicated can be read at the front and at the back of the machine.

A further purpose of the invention is to provide a means whereby a duplicate of all sales bearing a designatingmark of the salesman is present in the machine to be read by the proprietor at any time, so that if a sale is made for a given amount known to the proprietor and is not rung up on the machine the omission can be detected and the salesman guilty of the omission may be readily identified.

Another purpose of the invention is to provide a printing device which will operate to produce any desired advertising or display matter on the check delivered by the machine, which check is designed to be handed to the customer as evidence of the sale having been duly recorded and as a protection against an overcharge.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a vertical section taken practically on the line 1 1 of Fig. 4. Fig. 2'is a similar view showing the mechanism in a different position.

Fig. 3 is a section on the line3 3 of Fig. 4. Fig. 4 is a vertical longitudinal section through the machine. Fig.

5 is an enlarged sectional view taken practically on the line 5 5 of Fig. 3. Fig. 6 is a perspective view of the operating-lever. Fig. 7 is a longitudinal section of the indicatorwheels, their sleeves, and operating-gears and a side elevation of the shaft upon which they are mounted. Fig. 8 is an enlarged sectional elevation showing the arrangement of three bottom keys of a bank of keys. Fig. 9 is a bottom plan view of the upper three keys of a bank of keys and a portion of the locking-plate and its releasing means for the entire bank of keys. Fig. 10 is a cross-section taken practically on the line 10 '10 of Fig. 9. Fig. 11 is a front elevation of a portion of the casing, showing the means for operating the zero-keys ot' the mechanism; and Fig. 12 is a front elevation of the entire machine. Fig. 13 is adetailview of a ratchetand-pawl mechanism forming a portion of the construction of the machine, together with a bottom plan view of the pawl. 7

A represents the casing of the machine, which may be of any desired size. The said casing is provided with an end extension A, as is shown in Figs. 3 and 4, and the lower front portion A of the frame is preferably bowed or is rendered more or less convex, producing thereby a curved breast for the casing. In the breast portion A of the casing any desired number of banks of keys B is located, the keys of each bank being arranged one above the other and are adapted to be pressed inward and to bear upon their outer end surfaces figures designating the amount of sales, each bank of keys reading from 0, which is the lowest key, to 9, which is the uppermost key. In thedrawings four such banks of keys are shown, one bank expressing units, another bank tens, and the third bank hundreds. Adjacent to the first or right-hand unit bank of keys a 5 slot 10 is produced in the breast A extending parallel with the said bank of keys, and each key, with the exception of the lower or zero key, consists of an outer head-section 11 and a shank-section 12, which extend within the casing, the lower end of the shank-section at its upper edge being beveled, as is in ISO plates, as is shown in Figs. 8 and 9.

dicated at 13, especially in Fig. 8, and in the upper edge of each key adjacent to its inclined surface 13 a transverse slot 14: is produced. The zero-key, which is especially designated as I), differs from the other keys in the bank only in that the head 11 is omitted, and the zero-key is much narrower than the other keys where the slot 14 is produced. Otherwise the shanks of the zero-keys are of the same construction as the shanks of the other keys. This difference is clearly shown in Fig. 8. Adjacent to each bank'of keys a plate 15 is attached to the inner face of the breast A of the casing, following the curvature thereof and extending inward at a right angle to the breast, and at the inner edge of each plate 15 a guide-plate 16 is secured which is at a right angle to the body-plate 15, as is best shown in Fig. 10, and in the guideplates 16, which extend below the inner-ends of the banks of keys B, openings 17 are produced through which the inclined inner ends of thekeys pass. Upon each guideplate 16 a locking-plate 18 is mounted to slide, the locking-plates 18 and guideplates 16 being curved correspondingly to the curvatures of the breast A o f the casing. The locking-plates 18 do not extend the full width of the guideplates 16, as shown in Fig. 9, and the said locking-plates 18 are adjustably held in position by screws 19, passed through slots 20 into the guide-plates 16, the said slots being locking- The locking-plates 18 are provided with openings 21, produced at intervalstherein, as is shown in Fig. 9, and the inclined end portions of the keys B enter these slots 21, the forward walls of the said slots 21 being normally in engagement with the inclined surfaces 13 of the keys, as is illustrated in Fig. 8. The keys 13 are held in their normal or outer position by springs 22, which are loosely coiled around their shanks between the guideplates 16 and the breast A of the casing, as is especially shown in Figs. 8 and 10. The guide-plates 18 are held in the position just described relative to the keys B through the medium of springs 23, attached to the breast ofthe casing and to the upper ends of the guide-plates, as is shown best in Fig. 1, and

longitudinally produced in said when a key is pressed inward the guide plate through which the said key passes is caused to move upward against the tension of the spring 23, so that when the key is pressed sufficiently inward the upper wall of the slot in the guide-plate through which the key passes will enter the slot 14 in the key and cause the key to be automatically locked in its inner position. It is evident that as the zero-keys Z) are narrower than the other keys of the respective banks should the zero-key be pressed inward and its slot lat receive the upper wall of the locking plate or slide 18 and be locked in its inner position and should another key in the same bank of keys be pressed inward said other key would move the locking-plate -18 so far upward as to immediately release the zerokey from looking engagement with said plate.

A stop 24 is located at the lower end of the guide-plate '16, which is adjacent to the slot 10, or, in other words, the right-hand guidenear its center through which a pivot-screw 26 passes into an end of the rocking bar 28, which latter bar is pivoted at its center by means of a screw 20 or its equivalent to the under surface of the upper portion of the breast A of the casing, as is best shown in Fig. 9. The upper end of the trip-bar 25 is connected by a link 30, preferably of wire of suitable gage, with the upper end of the right-hand locking-plate 18.

A lever 0 extends through the slot 10, being provided with a suitable handle 44 at its outer end extending beyond the breast of the casing, as is shown in Figs. 1 and 2, and this lever C is secured upon a shaft 43, which extends through the said casing from end to end and is journaled in the end portions of the casing. Each bank of keys heretofore mentioned is provided with a similar leverC; but these latter levers are much shorter than the lever O and do not extend out beyond the breast of the casing, as is illustrated in Fig. 4.

At one side of the slot 10 in the breast A of the casing at the under side of said breast a rack-bar 31 is secured to the casing, the teeth 32 of the said bar being practically straight and transversely arranged, as is illustrated in Figs. 1 and 2, and this rack-bar 31 terminates short of the upper and lower ends of the said slot, for a purpose to be hereinafter described.

Just below the zero-keys b at the exterior of the breast A of the casing A a horizontal shaft 33 is mounted to turn in suitable bearings, and a stop-lug 3-1l extends down from the said shaft to limit the outward throw of the same. This shaft is provided with a se ries ofupwardly-extending fingers 35,adapted for engagement with the outer ends of the zero-keys I), and when the shaft 33 is rocked in one direction these fingers 35 press the zero-keys inward. At the right-hand end of the shaft an additional upwardly-extending finger 3G is secured to the shaft 33, the right-hand finger 35 being at one side of the slot 10 and the auxiliary finger 36 at the opposite side of the said slot. This auxiliary finger is adapted to be operated upon by the lever 0 when the said lever has been carried down to the lower end of the slot 10, and at such time, in a manner to be hereinafter described, the finger 36 is pressed inward and the shaft 33 is rocked in'the same direction, and the fingers 35 on the shaft are compelled to press the zero-keys inward to be locked by the locking-plates 18 in the manner hereinbefore specified, as at each full downward stroke of the lever 0 all of the ciphers on the indicator-wheels, to be hereinafter specified, are made visible at both the front and the rear of the machine.

A drawer D is mounted to slide in the bottom of the casing of the machine, as is shown in Figs. 1, 2, and 4. This drawer when not locked is forced outward by a spring 37 at the back of the casing havingbearing against the rear of the drawer. The drawer is locked in the casing usually by producing a lug 38 at the central portion of its upper rear end, which lug is adjustably attached to the drawer, as is shown in Fig. 2, and providing a spur 39 for engagement with the said lug 38, which spur is formed upon the lower longitudinal edge of an arm 40, pivoted to a bracket 41 at the rear of the casing. This arm 40 is held in position for locking engagement with the drawer when the drawer is out of the casing by means of a bracket 42, likewise attached to the rear of the casing and located beneath the pivotal end of the said arm 40. When the lever C, heretofore referred to, has been carried down to the lower end of the slot 10, the shaft 43, also heretofore mentioned, will be rocked and a crank-arm 40, extending from the shaft 43, will be carried upward to the position shown in Fig. 1 and will engage with the forward free end of the arm 40 and will raise the said arm from locking engagement with the drawer.

The outer shaft 33 is operated by means of a lug 45, which extends from the handle 44 of the lever O, and said lug, as is shown in Fig. 1, when the hand-lever C is pressed downward is brought to an engagement with the outer upper surface of the finger 36 onthe shaft 33, such surface of the finger being more or less rounded off.

In order that the hand-lever 0 cannot be moved upward while it is being carried downward to its lowest position and cannot be moved downward when it is carried upward to its full upper position, a pawl 46 is pivotally attached to one side of said hand-lever, and at the heel of the pawl a spring 47 is attached, the said spring being suitably held and guided by the hand-lever, as is shown in Figs. 1, 2, and 4. When the hand-lever O is inits upper or normal position, (shown in Fig. 2,) the pawl 46 will be beyond the upper end of the rack-bar 31, and as the hand-lever is moved downward the pawl will slip over the teeth of the rack-bar; but if an effort be made to draw the hand-lever O backward the pawl will enter the most convenient tooth in said rack-bar and prevent further movement of the hand-lever to the upper position, coinpelling the operator to continue the movement of the hand-lever to its downward position. When the hand-lever reaches such position, as is shown in Fig. 1, the pawl 46 will have passed by the lower end of the rackbar 31. When the hand-lever is to be again carried upward, the pawl 46 will slide by the teeth of the rack-bar 31; but if an attempt be made at such time to again force the handlever downward before it has reached the limit of its full upward stroke the pawl 46 will engage with a convenient tooth on the rackbar 31 and prevent such movement. At the opposite side of the hand-lever C and at the corresponding side of each of the other levers O a bracket 47 is constructed, and a pawl 48 is pivoted to the bracket. The said pawls 48 are each provided at the free end with a tooth 49, V-shaped in cross-section, and the teeth 49 of the pawls 48 are held by means of springs 49 in engagement with teeth formed upon segments 50, secured to one face of the wheels 51, one of said Wheels being loosely mounted on the shaft 43 adjacent to the lever O and the shorter lovers 0. At the opposite side of each wheel 51 an indicator-arm 52 is rigidly secured. Each indidicator-arm 52 has a recess in its upper end, in which recess a pawl 53 is pivoted, and these pawls are oppositely inclined at their ends, and their inner ends are normally held against an inclined shoulder formed on the indicator-arm carrying the pawl by means of springs 54, as is shown best in Fig. 2. These pawls 53 can move upward at their outer ends against the tension of the springs 54; but should an attempt be made to force the pawls 53 down- .ward out of alinement with the indicatorarms carrying them the contact of their inner inclined ends with the corresponding inclined shoulders mentioned will prevent such movement. These pawls 53 in the downward movement of the indicator-arm will slip by the inner projecting end of a key which has been pressed; but on the upper or return movement of the indicator-arm 52 the pawl of such arm will be brought in engagement with the inner projecting portion of the depressed key, as is shown in Fig. 2, and will not pass by the same; but the hand-lever C may becontinued on its upward movement, since the engagement between the tooth 49 of the pawl 48, carried by said hand-lever C, and the toothed segment 50 of the wheel 51 belonging to said lever is sufficient to cause the said lever and indicator-arm to move together, while the indicator-arm meets with no resistance; but the moment that resistance is offered to the movement of the indicator-arm the locking connection between the lever and the segment 50 is broken and the indicator-arm remains stationary, while the hand-lever is continued in its upward movement, so that the indicator-arm will only move the indicator-wheel to the extent of the distance between the zero-key of a bank and the key which has been pressed inward. As, for instance, if the key marked 5 in the first bank is pressedinward, which is done before the hand-lever is moved from its upper position, the hand-lever and its accompanying indicator-arm, if the two he in looking engagement at such time, will move downward together, the pawl 53 of the indicator-arm passing-by the projecting end of thekey at the downward movement of the said arm, and when the indicator-arm 52 reaches its lowest position in engagement with the stop 24 the hand-lever will have operated the shaft 33 and caused the fingers 35 to press all of the zero-keys inward, thus causing a cipher to appear at the opening in the casing of each of the indicator-wheels, and the pawl of the registering-arm 52 will at that time be back of the inner end of the zero-key. The moment that the hand-lever O is moved upward the fingers 35 will be relieved from pressure and the zero-keys will be carried outward by means of their connected springs, and the indicator-arm and hand-lever will now move upward together until the pawl of the handlever engages with the inner end of the depressed key 5, where the said indicator-arm will stop, but the hand-lever will be carried upward. When the hand-lever reaches the trip-bar 25 and presses against the same, the locking-plate 18 will be drawn upward, and the depressed key will be released and permitted to return to its normal position, and the indicator-wheel belonging to the bank of keys operated will have been moved five digits only, showing the figure 5 instead of a cipher, while all of the other indicatorwheels displaya cipher until one of the keys of the bank belonging to said wheel is pressed inward to indicate a sale.

It may be here noted that the locking-plates 18 for the tens and hundredskeys are provided with springs 23, heretofore described, to keep the said plates in position for locking engagement with depressed keys and that each locking-platej ust referred to is provided with an attached trip-bar 25, also heretofore described and shown in Figs. 1 and 2, which when engaged by the levers 0 upon their upward movement releases the depressed keys from looking engagement with the lockingplates 18.

At the under side of each indicator-arm 52, operating in connection with each short lever O, and likewise the indicator-arm operating in connection with the hand-lever O, a block 55 is adjustably secured to the under or forward longitudinal edge of the hand and ass'ociate levers a suitable distance from the shaft 43. A shoe 56 is attached to each of said blocks 55, as particularly shown in Figs. 1 and 2, and the said shoes extend upward from the indicator-arms 52 and adjustably carry bars 57. At the upper ends of said bars 57 rack-teeth 58 are formed at their under or rear longitudinal edges, adapted for engagement with pinions, to be hereinafter described, on an indicator-shaft 59, which shaft is journaled in the left-hand end of the main casing A at the rear of and above the breast A as is shown in Figs. 1, 2, and 4. Near its opposite or right-hand end the shaft 59 is journaled in a projection X, which divides the main portion of the casing from the extension A, the said shaft 59 at its right-hand end extending into the chamber formed by said extension A, as is particularly shown in Fig. 4. This shaft carries at its left-hand end a wheel 75, upon which wheel Roman characters are produced-reading, for example, fromItoXorXII-and this wheel 75 may be denominated the operators wheel, since it carries characters which will designate the persons operating the machine. The shaft 59 likewise carries any desired number of indicator-wheels. In the drawings three of such wheels are illustrated as mounted on the shaft 59namely, a hundreds-wheel 60, a tens-wheel 65, and a units-wheel 70-each of which wheels has independent action on the said shaft. Each wheel 60, 65, 70, and 75 is divided peripherally into two sections 0 and 0, preferably by a central dividing-line, and on said indicator-wheels figures are produced, reading from O to 9, inclusive. These figures in the divisions of the said indicatorwheels read in opposite directions and are reversely produced. For example, when the O in one division of an indicator-wheel appears at the reading-opening a at the upper front portion of the casing the 0 in the other division of the same wheel will appear at the opening a. at the back of the easing and in transverse alinement with the opening a, and the same order is preserved relative to the Roman characters on the operators wheel 75.

The left-hand or hundreds-indicator wheel 60 is provided with an attached hub-sleeve 61, which extends loosely along the shaft 59 to a point near its right-hand end, as is shown in Fig. 7. At the right-hand end of this sleeve a gear-wheel 62 is secured for a purpose to be hereinafter mentioned. At-a suitable distance between the tens-indicator wheel and the hundreds-indicator Wheel 60 two pinions 63 and 64 are secured, the pinion 63 being adapted for engagement with the rack-teeth 58 of the bar 57, connected with the lever mechanism belonging to the aforesaid hundreds-wheel. The tens-wheels 65 is provided with an attached hub-sleeve 66, which extends loosely over the hub-sleeve 61 of the wheel 60 and terminates at a point short of the right-hand end of the hub-sleeve 61, as is also shown in Fig. 7. At the righthand end of the hub-sleeve 66 a gear 67 is secured, while between the units-wheel and the tens-wheel 65 two pinions 68 and 69 are produced upon the aforesaid hub-sleeve 66, the pinion 68 being operated from the rackbar 57, connected with the lever mechanism belonging to the tens wheel. The unitswheel 70 is likewise provided with an attached hub-sleeve 71, which extends loosely over the hub-sleeve 66 and stops short of the right-hand end of the said sleeve 66, as is also shown in Fig. 7. At the right-hand end of the hub-sleeve 71 for the units-wheel a gear 72 is secured, and adjacent to the said gear 72 in the said hub-sleeve 71 circum ferential apertures 73 and 74: are produced, corresponding to the pinions 63, 64, 68, and 69, as the aforesaid pinions and the hub-sleeve 71 are of the same diameter. The apertures 73 are adapted to receive the rack of the bar 57 belonging to the units-wheel, which latter rack-bar is directly operated through the movement of the hand-lever G. The gears 62, 67, and 72 are of the same diameter, and on the shaft 59 between the operators wheel 75 and the hundreds-wheel 60 a pinion 76 is secured of the same diameter as the pinions 63, 64, 68, 69, 73, and 74. This pinion 76 is adapt-ed to be engaged by a rack-bar 57, connected with a lever C of the same construction and having the same connections as the intermediate levers C, heretofore described. Through this rack connection with the pinion 76 the operators wheel is made to re-' volve simultaneously and in the same direction as the indicator-wheels 60, 65, and 70, and at the extreme right-hand end of the shaft 59 a gear 77 is secured, adapted to operate a printing mechanism used in connection with the operators wheel 75.

A series of horizontal brackets 78 is carried from the inner surface of the upper front portion of the main casing, as is shown in Figs. 1, 2, and 4, and at the inner ends of these brackets shafts 79 are mounted to turn. On each shaft 79, between the bracket-bearings therefor, a guide-roller 80 is mounted to loosely turn, against which the forward or plain surfaces of the rack-bars 57 engage. These guide-rollers serve to hold the teeth of the rack-bars in engagement with their respective pinions on the shaft 59. Each shaft 79 has also secured to it a gear-wheel 81, and the gear-wheels 81 on the respective shafts 79 are adapted to mesh, respectively, with the pinions 64c, 69, and 74 on the shaft 59. These gear-wheels 81 are adapted to communicate motion to the registering or total-adding mechanisms E, which total-adding mechanisms may be of any approved type, one being provided for use in connection with the unitswheel 70, another for use in connection with the tens-wheel 65, and a third mechanism being employed in connection with the hundreds-wheel 60. These mechanisms are suitably mounted on shafts 82, carried by the aforesaid brackets 78, and include pinions 83, which mesh with the teeth of the gear-wheels 81. The faces of the disks of the said totaladding mechanisms are read at openings 84, produced in the upper front portion of the casing A, as is shown in Fig. 1. Thus it will be observed that at each registering movement of an indicator-wheel the amount represented by such registration will be recorded on the total-adding mechanism acting in con junction with such wheel.

In the upper portion of the chamber formed by the extension A at one end of the casing and below the end of the shaft 59, extending into said chamber, a shaft 85 is mounted to turn, extending from one end of the chamber to the other, as is shown in Fig. 5. At the inner or left-hand portion of the shaft 85 printing wheels or disks 86,87, 88, and 89 are mounted, and corresponding printingwheels are also mounted on said shaft near and at its right-hand end, reading from left to right in the following order: 86, 87, 88, and 89 The printing wheel or disk 86 has type-matter correspondingyet in reverse order to that on the indicating-wheel 70, and the printing wheels or disks 87, 88, and 89 have type-matter on their peripheral surfaces corresponding to the type-matter produced on the peripheries of the indicator-wheels 65 and 60 and the operators wheel 75', respectively, but in reverse order and in single arrangemen t. The printing-wheel 86 corresponds to the units-indicator wheel 70, the printingwheel 87 to the tens-indicator wheel 65, and the printing-wheel 88 to the hundreds-indicator wheel 60, while the fourth printing-wheel 89 corresponds to the operators wheel 75. The second set of printing wheels or disks are arranged in reverse order on the said shaft, the auxiliary printing-wheel 89 being connected with the check-printing wheel 86 and the indicatorwheel 70, the auxiliary printing-wheel 88" being connected with the check-printing wheel 87 and the indicatorwheel 65, while the printing-wheels 87 and 88 are connected with the indicator-wheel 60 and the printing-wheels 86 and 89 with the operators wheel 75. The first or primary set of printing-wheels, or those to the left, are adapted to print upon a check to bedelivered to the purchaser, while the second orauXiliary set of printing-wheels (those to the right) are adapted to print duplicate matter upon the ribbon or tape which remains in the machine. Each of the primary or check-printing Wheels 86, 87, 88, and 89 is provided with peripheral teeth 90, and the teeth on said printing-wheels mesh, respectively, with the proper gears 72, 67, 62, and 77, carried by the right-hand end portion of the indicator-shaft 59. The printing wheel or disk 86 is secured directly to the shaft 85 at its left-hand end, and at the right-hand end of said shaft the printing wheel or disk 89 of the second set is secured. A hub-sleeve 91 is secured to the printing wheel or disk 87 of the first set and loosely surrounds the shaft 85, extending near the left-hand end of said shaft, and to this sleeve 91 the printing wheel or disk 88 of the second set is secured. A hub-sleeve 92 is likewise secured to the printing wheel or disk 88 of the first set and loosely extends over the aforesaid hub-sleeve 91, terminating short of the right-hand end of the latter, and at the right-hand end of the said hub-sleeve 92 the printing wheel or disk 87 of the second set is secured, while the printing wheel or disk 86 of the second set is secured to the right-hand end of a hub-sleeve 93, mounted to turn upon the hub-sleeve 92. This outer hub-sleeve 93 is secured to the printing wheel or disk 89 of the first set, as is clearly shown in Fig. 5.

Below the two sets of priming wheels or disks above described two plates 94 and 95 are arranged side by side, as is shown in Figs. 3 and 5, being suitably attached to convenient surfaces'of the chamber formed by the extension A, and the said plates extend in direction of the front and rear of the casing. These plates 94 and 95 are practically tables to support and guide the tape or checks to be printed, and both of them at their rear ends are downwardly and forwardly curved, as is shown in dotted lines in Fig. 3;; but the plate or table95 at its forward end is straight and leads tothe opening 96, through which the printed check is adapted to pass to be delivered to the purchaser, while the forward end of the opposite table 94 is downwardly curved and is a predetermined distance from the inner face of the upper portion of the chamber of the extension A, as is shown in Fig. 3, the curvature of the rear ends of both tables being illustrated in Fig. 5.

Just above the upper rear end portions of both tables 94 and 95 an upper correspondingly-curved guide 98 is located, so that the material to be printed may be suitably guided in its upward'movement over the said tables, and beneath each set of printing rollers or disks an inking-ribbon 99 is located, wound 7 upon suitable supports, as is shown in Fig. 3.

The tape or ribbon 100, that is adapted to pass over the table 94, is printed bythe first or inner set of printing rollers or disks and passes over a suitable reel 101, supported by a shaft 102, as is shown in Fig. 5, up over the table 94,and down around the forward curved 1 portion thereof, as is shown in Fig. 3, to an engagement with a drum 103, mounted on a shaft 104, which extends through the parti- 7 tion X into the main chamber of the casing,

as is shown in Figs. 1 and 2, and at the inner end of the shaft 104 a ratchet-wheel 105 is se- 7 cured, engaged by a suitable pawl 106.

Below the rear curved portion of the table 95 a shaft 107'is journaled in the extension A, and on the said shaft a corrugated feedroller 108 is secured, as is shown in Figs. 3 and 5, and in a box projection 109 from the extension A of the casing a gear-wheel 110 is located, attached to the right-hand end of the aforesaid shaft- 107.

Horizontally opposite the said extension A, as is shown in Fig. 3. Below the larger feed-roller 108 a bed-roller 113 is suitably mounted on a shaft 114, the bed-roller being adapted to act in conjunction with and is horizontally opposite to the also suitably mounted.

impression-roller 114, carried by a shaft 115,

Below the said impression-roller a suitablyemounted inkingroller 116 is located, as is shown in Fig. 3.

The shaft 115, carrying the impression-roller 114, is provided with an attached gear 117, which meshes with the gear 110. The impression-roller 114 is adapted to print an advertisement or instructions upon a ribbon 118, which is wound around a suitable support 118 at the lower portion of the said extension A of the frame, and this ribbon passes upward between the bed-roller 113 and theimpression-roller 114, thence upward between the feedrollers 108 and 111, up over the table 95, and thence out through the opening 96. The said ribboniafter having been printed upon by the impression-roller 114 is then printed upon by the'printing rollers or disks of the second set, (shown in Fig. 5,)

mounted on the shaft 85, and while receiving this latter impression the end of the ribbon or tape will extend out a suitable distance through the opening 96, enabling'the tape to be grasped by the operator and removed in the form of'a ticket or check after the printed portion of the ribbon. has been severed from the main portion of the ribbon by means of a suitable cutting mechanism to be hereinafter described. 8

The tables 94 and 95 are provided with transverse openings 120 at about their central portions, through which vertical platens 119 may extend to forin a support for the tapes while being printed upon by the two sets of printing devices operated directly from the shaft 59 and shown particularly in Fig. 5. These platens 119 are each secured to a vertical rod 121, mounted to slide in vertical boxes 122 against the pressure of springs 123,contained in said boxes,and these boxes are h'eldin position within the extension A of the casing by suitable cross-bars 124. A rod 125 connects the two vertical rods 121, and the said rod 125 at one end extends out through and beyond'a vertical slot 126 in the partition X between the outer chamber of the casingand the inner or main chamber' of the same.

The printing mechanism is actuated in the following manner, as is shown particularly in Figs. 1 and 2, in which it will be observed that a lever-arm 127 is about centrally pivoted on the inner surface of the partition X and is held normally in the horizontal position shown in Fig. 2 by means of a spring 127 at its rear end: The forward end of this lever-arm 127, when the hand-lever O is carried downward, is raised to the position shown in Fig. 1 by engagementwith a crank-arm 128 from the shaft 43, as is shown in Fig. 1, and when this lever-arm 127 is thus elevated a dog 129, held by a spring 130 against the ratchet-wheel 105 on the shaft 104, will turn thisratchet wheel and will operate the drum 103 to draw the tape 100 from the drum'101 and'across the table 94. In this manner the tape which is to remain as a record in the machine is shifted. The mechanism operating upon the tape 118, from which the check is to be out, is operated in the following manner: A pitman 131 is pivoted to the rear end of the lever-arm 127 and is connected at its upper end to a link 132, which is loosely mounted on the shaft 107, on which the larger feed-roller 108 is secured, and at the inner end of this shaft 107 a ratchet-wheel133 is secured. The dog 134, carried by the link 132, engages with the teeth of this ratchetwheel133,which teeth are likewise engaged by a pawl 135 to prevent back movement of the said shaft. In this manner motion is communicated to the feed-roller 108 and through the gear 110 to the gear 117, and consequently to the impression-roller 114. A duplicate impression from the printing-Wheels 60, 65, and in action and likewise a duplicate impression from the operators wheel in action are produced upon the tapes 118 and 100 simultaneously in the following manner: A link 135 is vertically located upon the outer face of the partition X, as is shown in Figs. 1 and 2, and is pivotally attached to an extension 134 from the lever-arm 127. This link 135 is provided with slots through which screws 136 pass into the said partition X for the purpose of guiding the movement of the said link in an upward and downward vertical direction. In the upper slot of the said operating-link 135 the inner projecting end of the rod 125, connectingthe vertical or plunger rods 121, enters. Across the upper portion of the operating-link 135 a horizontal sliding plate 137 is suitably mounted on the outer face of the aforesaid partition X, as is also shown in Figs. 1 and 2, and in the upper edge of this sliding plate 137 an L-shaped slot 138 is produced, one upper wall of which slot is more or less inclined. This sliding plate 137 is held in a rearward position by engagement with a spring 139, secured to any convenient fixed support, as is shown in the same figures. From the forward end of the sliding plate 137 an arm 140 is carried upward, and this arm 140 is connected by a wire of suitable gage or a link 141 with the rocking bar 28, upon which the trip-bar 25 is pivoted, which trip-bar, as has been stated, is opposite the slot 10 in the casing in which the hand-lever C travels. It will be understood that at the downward movement of the handlever O the lever-arm 127 is elevated to the position shown in Fig. 1 by engagement with the crank-arm 128, extending from the shaft 43, and at such movement of the hand-lever O the tapes 100 and 118 are fed in a forward direction, and an impression is made on the tape 118 through the medium of the impression-roller 114. \Vhen the hand'lever C is carried to its upper position (shown in Fig. 2) and engages with the trip-bar 25 to release the depressed key, the said trip-bar in its rearward movement operates through the link or wire 141 on the sliding plate 137 to force the said plate rearward. At this time it may be remarked that in the upward movement of the lever-arm 127 the link 135 is drawn downward and carries with it the inner extending end of the connecting-rod 125 for the rods or plungers 121 of the platens 119, and the said rod 125 will then travel down in the slot 138 and will be locked in the lower portion of the said slot. When the said lever-arm acts upon the trip-bar 25 to force the same rearward, and thus produce a forward movement of the sliding plate 137, the said projecting end of the connecting-bar 125 is free to leave the slot 138 in the plate 137 and does so through the action of the springs 133, compressed by the downward motion of the platen or plunger-rods 121, and the platens 119 instantly rise to form a bed for the support of the tapes on the tables 94 and 95, thus efiecting an impression on the said tapes through the medium of the two sets of impression rollers or disks. (Shown particularly in Fig. 5.) As soon as such an impression is made a spring 142, which is attached at its ends to the two tables 94 and and has bearing upon the connecting-rod 125 of the plunger-rods for the platens 119, forces the said rod 125 downward, so as to remove the platens from the tapes and 118, thus preventing the printed matter from being blurred. The said spring 142 serves to normallyhold the said platens 119aslightdistance from the impression-surface of the printing rollers or disks in the two sets operated from the shaft 59.

Immediately after the printing process just described has been performed the printed portion of the tape 118 is automatically severed from the body of said tape through the action ofacuttingmechanism,whiohouttingmechanism is as follows: A crank-arm 142 is secured to the shaft 43, operated through the medium of the hand-lever O, and this crank-arm 142 is at an angle to the crank-arms 40 for releasing the drawer and the arm 128, which operates the printing and feeding mechanism. This crank-arm 142 is within the end extension of the casing and is clearly shown in Figs. 3 and 4. When the hand-lever O is brought to its upper position, (shown in Fig. 3,) this crank-arm 142 presses down upon the forward end of a crank-lever 143, pivoted at about the central portion of this lower horizontal member by a suitable pivot-pin 144,

ICO

and when the said crank-lever 143 is in its lower position it rests upon a pin 145, being drawn down in the direction of the said pin by a suitably-attached spring 146. At the upper rear end ofthis angle or cranklever143 the shank 147 of a knife-blade 147 is pivotally attached. The said shank and knife are so formed that the shank will extend up in front of the corrugated feed-roller 108, and the knife will engage with the printed portion of the tape 118 to out the same at the opening in the table 95, the tape being severed to form a check for delivery slightly to the rear of the upper printing rollers or disks operated from the shaft 59, which produce the impressions on the said tape, as is shown best in Figs. 3 and 4.

It will be understood that a bank of keys B is also provided for use in connection with the operators wheel 75 and that this latter bank of keys is of thesame construction and is operated in the same manner as the banks of keys for the printing-Wheels; but the bank of keys operated in connection with the operators wheel bear upon their heads characters corresponding to the characters upon the operators wheel 75, which characters are preferably Roman numerals.

In the complete operation of the machine when a sale is made the salesman will press inward a key in the operators bank of keys bearing his designating numeral or character and will then proceed to press in the keys of the other banks corresponding to the units, tens, orhundreds representing the sale. Next the hand-lever C is carried downward to its full lower position, and, as stated, at this time all of the printing-wheels will have been revolved to expose 0 at the sight-openings of the machine. At such time the tapes 100 and 118 are fed forward, and the tape 118 is printed with advertising or other matter through the medium of the impression-roller 114. On the upward movement of the hand lever O the respective printing-arms 52 will stop at the depressed keys, and the various printing-wheels will then be turned to present at the sight-openings the figures corresponding to the figures on the keys which have been depressed. The hand-lever O is then continued upward to its full upper position, at which time, as has been stated, by engagement with the trip-bars 25 the depressed keys are released, and the platens are carried upward to cause an impression to be made upon both of the tapes, thus securing a record of figures representing the sale that has been made and the designating character of the salesman. At the same time the knife 14:7 acts to cut the printed tape from the ribbon 118, forming a check, which check can be readily removed from the machine to be given to the purchaser, while a record of the sale is preserved in duplicate on the ribbon 100, which remains in the machine for the inspection of the proprietor.

In the operation of the machine it will be understood that when the proper value-keys are depressed and the lever G is drawn downward all of the zero-keys are automatically depressed, and these latter keys are so narrow that such action does not release the value-key already depressed.
